1KW PA LCD Functions
The LCD is used to display information on the operational conditions of the 1KW amplifier, and
status information. The LCD comprises 2 rows, and therefore it is necessary to split the
information on four different display pages of 2 rows each.
The first row of each page always presents two items:
The current mode indicator, RX or TX
The operating frequency, in MHz, as detected during the tuning process. The frequency
is measured with a resolution of 10 kHz, and therefore, if you need to know the exact
transmit frequency, always use the RM125/RM125R frequency display.
The information displayed in the second row changes with the specific page. To select a page,
press the DISPLAY MODE push-button display as required (scrolling is cyclical). The selected
page remains on display, until you select another page.
The information presented on each page is explained in the following table. The pages are
presented in the order they appear when scrolling by means of the DISPLAY MODE push-button.
The following table lists the 1KW PA LCD Functions

Typical Page
Function
1
Normal receive screen.
When transmitting (TX), the second row displays the forward (FWD)
power in watts, followed by the VSWR.
2
Alternative screen: when transmitting, displays the forward (FWD) and
reflected (REV) power in watts.
3
Status screen (shown for receive – RX – mode). Displays the total number
of faults and warnings detected in the unit. If either number is not 0, the
FAULT indicator indicates the condition with the highest severity:
If the condition with the highest severity is a warning (FAULTS is
0, WARNING is not 0), the FAULT indicator flashes
If the condition with the highest severity is a fault (FAULTS is not
0), the FAULT indicator lights steadily
4
Fault (F) or warning (W) screen: displays the fault and /or warning
detected in the unit.
Frequency appears only after successful tuning: before tuning,
and also in case the tuning fails, no frequency is displayed. For
example:
The forward and reflected power (or VSWR) values are automatically updated; fault and warning
information is refreshed only after scrolling again to the same page.
